Certainly worth visiting, this website hosts an encyclopedia's worth of information on ship wreck anatomy, marine biology, and diving locations around New Jersey. A variety of species are displayed here, from Sand Tiger sharks to striped bass, AND it includes dozens of linked maps of coastal areas of New Jersey.
This is a map, with links to more maps, which have links to even more maps. Upon clicking on a specified location, you get information on depth, species, artifacts found, history of the ship wreck (if the site is a ship wreck), potenital hazards, visibility, comments, and so much more.
I was not aware previously of what New Jersey had to offer in terms of scuba sites, but now I know. There are thousands, which are mainly ship wrecks, filled with artifacts and rich historical tales.
Also on this site is a variety of information on oceanic environmental conditions here in Jersey.
Everything from types of fishing vessels to decimation of species, this site has it all.
Definitely check it out!
